Application filed May 25,1905. Serial No. 262,267.

` molds for forming vaults of concrete or other plastic material; and it consists in the novel construction, combination, and arrangement of parts hereinafter shown and described.

The object of the invention is to provide a simple, inexpensive, durable,and eflicient sectional mold of this character which may be quickly set up for use and knocked down to facilitate its removal from the molded structure.

The above and other objects, which will appear as the nature of my invention is better understood, are accomplished by means of the construction illustrated in the accompanying drawings, in which- Figure l is a vertical longitudinal sectional view through a vault-mold constructed in accordance with my invention. Fig. 2 is a horizontal sectional view through the same, taken on the line 2 2 in Fig. 1. Fig. 3 is a detail sectional view, on an enlarged scale, taken on the line 3 3 in Fig. 1; and Fig. 4 is a detail sectional view taken on the line 4 4e in Fig. l.

The embodiment of theinvention illustrated in the drawings is adapted for forming vaults and' foundations of superstructures and comprises a plurality of sections 2, which are detachably connected. As shown, the mold'is of. rectangular `form and is composed of ten sections, three being on each side and two at each end. Each of the sections comprises a body portion 3 of suitable width and length and preferably formed of sheet metal. Along one of the longitudinal edges of each section is formed an oifset portion 4, which is adapted to overlap the adjacent edge of the contiguous section. These offset portions 4t are adapted to abut against the ends of metallic battens or cleats 5, which are riveted or otherwise secured transversely across the inner faces of the bodies or plates 3 at suitable intervals. The portions 4 are held in engagement with the battens 5, and the sections of the mold are held rigidly in alinement with each other by fastening devices 6, which are preferably in the form of hooks, pivoted at one of their ends, as shown at 7, upon the battens of one section and adapted to engage headed studs or pins 8 upon the battens of` the adjacent or contiguous section. These hooks 6 are preferably formed of at metal and have notches or recesses 9 in their free 'ends to engage the pins or studs 8.

The outermost sections 2EL of each sideof the mold are preferably formed at one of their sides with right-angularly-bent portions or ianges 10, which are adapted to e'ngage the outermost sections o f the ends of the mold, as clearly shown in Fig. 'of the drawings. The sections at .the corners of the mold are held to-l gether by hooks ll, which are pivoted in eyes l2 and are adapted to engage headed studs 13.

lIn using the mold a hole is made in the earth larger than the mold, and the sections are then set up on end in the hole and locked together. The space between the sides of the hole and the outer faces of the mold is then filled in with concrete or other plastic material from which the vault or other structure is to be formed, and after this material has become set or hardened the mold may be readily removed by detaching its sectionsfrom each other. It will be seen that owing to the manner in which the mold-sections are secured together a rigid mold is produced which may be quickly set up or knocked down, as desired.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The herein-described mold comprising the plurality of sections each having one edge offset laterally to overlap the opposing edge of the next adjacent section, the battens disposed my hand in presence of two subscribing wit- A nesses.
